About the JBL 47HC In-Ceiling Speaker

The JBL Control 47HC is a premium in-ceiling professional loudspeaker designed for applications that require a focused beamwidth pattern along with very consistent coverage. Featuring JBL's conical Radiation Boundary Integrator (RBI), the RBI provides a large waveguide for the tweeter while low-frequency sound projects through specially designed apertures in the RBI, allowing for a seamless integration of coverage between the two coaxially mounted drivers. The result is extremely consistent sound character with very little variation throughout the listening space. The Control 47HC's narrow coverage pattern makes the system ideal for high ceiling applications where the focused pattern helps minimized time arrival anomalies from adjacent loudspeakers, resulting in improved speech intelligibility.

The large backcan on the Control 47HC along with the LF driver design provides extended bass response for a warm full-bodied tone. The system's 165 mm (6.5") woofer features a polypropylene cone and pure butyl-rubber surround for long life. The copper-clad aluminum voice coil wound on a vented aluminum former provides low distortion and high sensitivity. The coaxially mounted 25 mm (1") soft dome features internal damping for smooth extended response and ferrofluid cooling for enhanced power handling and reduced power compression. The result is crisp, clear highs.

Ideal for small and large projects alike, the Control 47HC is switchable for use as either an 8-ohm low-impedance speaker or as part of a 70V/100V distributed loudspeaker system.
